Question

y=x^2 - 25 What are the Roots: x= ? Vertex? and Axis of symmetry? Please help thank you ^_^

Answer 1

to solve for the "roots" means write
\[x^2-25=0\] and solve for \(x\)
it should take exactly two steps
\[x^2=25\] is the first one

Answer 2

second is to take the square root
don't forget the \(\pm\)

Answer 3

oh, so would the answer be -5 and +5?
